Educational Pearls:

  • Wide-complex tachycardia is defined as a heart rate > 100 BPM with a QRS width > 120 milliseconds

  • Wide-complex tachycardia of supraventricular origin is known as SVT with aberrancy

    • Aberrancy is due to bundle branch blocks

    • Mostly benign

    • Treated with adenosine or diltiazem

  • Wide-complex tachycardia of ventricular origin is also known as VTach

    • Originates from ventricular myocytes, which are poor inherent pacemakers

    • Dangerous rhythm that can lead to death

    • Treated with amiodarone or lidocaine

  • 80% of wide-complex tachycardias are VTach

    • 90% likelihood for patients with a history of coronary artery disease

  • In assessing a wide-complex tachycardia, it is best to treat it as a presumed ventricular tachycardia

    • Treating SVT with amiodarone or lidocaine does no harm

    • However, treating VTach with adenosine or diltiazem may worsen the condition
